CHARLES DONALDSON, 0F COUDERSPORT, PENNSYLVANIA, ASSIGNOR OF ONE-HALF T0ELMER E. MYERS, OF COUDERSPORT, PENNSYLVANIA.

OIL AND GAS BURNER.

To all whom it may concern:

Be it known that I, CHARLES DONALDSON, citizen of the United States,residing at Coudersport, in the county of Potter and State ofPennsylvania, have invented certain new and useful Improvements in Oiland Gas Burners, of which the following is a specification.

This invention relates to 011 and gaseous fuel burners and refersparticularly to a novel construction of the same.

An object of this invention is to construct a burner of this typewherein a small amount of fuel is consumed in comparison with the heatproduced, thereby providing a burner which is economical for practicalpurposes.

The invention further contemplates the construction of a burner of thischaracter wherein an intense heat may be produced on account of theregulating means employed whereby the proper proportions of air and oilor gas may be obtained and kept at a constant proportion.

The invention has for a still further obj ect the provision of a burnerof this character whlch is so constructed that the same may be employedfor the combustion of gas or of oil and to provide means for regulatingthe admission of oxygen to the gas or oil before the combustion of thesame, to thereby produce a complete burning of the fuel and a consequentintense heat.

Fora full understanding of the invention reference is to be had to thefollowing de scription and accompanying drawings, in Which:-

Figure 1 is a longitudinal vertical section through the complete burner.Fig. 2 is a view of the same disclosing the burner in a partially closedposition to limit the flow of air into the same. Fig. 3 is a detailedview of the improved valve located within the burner disclosing afragmentary view of the body of the burner disposed thereabout. Fig. 4:is a detailed perspective view of the improved inlet pipe, and Fig. 5 isa side elevation of a portion of the burner disclosing a modified formof adjusting means for controlling the air inlet. Fig. 6 is alongitudinal central sectional view through Fig. 5.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

Referring to the drawings the numeral 10 Specification of LettersPatent.

the inlet pipe 14.

which is provided internally with threads for engagement upon a threadedportion of The inlet pipe 15 comprises a length of pipe of commonformation which is closed at its forward end by a disk 15, the disk 15being provided with a plurality of apertures formed therethroughadajacent the edge of the same for the purpose of admitting of the flowof gas or air from the pipe 14.. The inlet pipe 14: is threaded upon itsforward extremity and is provided with a sleeve 16 which is threadedlyengaged therewith and which is provided with a web 17 annularly formedintermediately thereof for the purpose of providing a shoulder 18 toabut against the disk 15 and to close the aperture formed tl'ierethroughat times. For the purpose of forming a tight joint between the shoulder18 and the disk 15 a gasket 19 is positioned upon the shoulder 18 andimpinged between the same and the end of the inlet pipe 1 1. The sleeve16 is reduced at its forward end for the reception of a circular shank20 which carries an outwardly flared portion or disk 21 to form a valvefor engagement in the forward end of the body portion 10 to close accessof air thereto through the opening 11. The body portion 10 is providedforwardly of the opening 11 with an annular bead 22 against which thedisk is engaged in order to substantially seal the passage into theforward end of the body portion 10. The shank 20 is centrally andlongitudinally bored and threaded for the reception of a nipple 23 whichis positioned therethrough and extended forwardly therefrom for thepurpose of conducting the gases or air from the inlet pipe 14 into theforward end of the body portion 10. The nipple 23 is re tained inadjusted position within the shank 20 by means of a jam-nut 24 which isengaged over the forward end of the nipple 23 and impinged against thedisk valve 21.

The body portion 10 is provided with an inlet pipe which admits oil intothe same and which is provided with a valve 26 for regulating the flowof oil.

In the modification disclosed in Fig. 5 the inlet pipe 27 is providedwith a loose sleeve 28 which is flared at its forward end and threadedinternally for engagement over the rear extremity of the body portion 29which is externally threaded and is engaged to support the forwardflared end of the sleeve 28 rigidly thereto. The sleeve 28 is furtherprovided with a set-screw which is extended inwardly through one side ofthe same and is engaged against the outer face of the inlet pipe 27 toretain the sleeve 28 from sliding movement. From this construction it isreadily observed that when it is desired to move the inlet pipe 27 intothe body portion 10 the set-screw 30 is released and the properadjustment is made when the set-screw 30 is again tightened and causesthe retention of the inlet pipe 27 in such position.

In operation when the burner is adjusted as is disclosed in Fig. 1 thegas or compressed air is introduced through the inlet pipe 14 and causedto flow through the openings or ports formed in the disk 15 and to passcentrally through the sleeve 16 and into the nipple 23 where it isdischarged into the forward end of the body portion 10 causing a suctionthrough the opening 11 and thereby feeding a quantity of air through theopening 11 into the forward end of the body portion 10. At the same timethe valve 26 is opened to admit of the flow of oil through the pipe 25into the forward end of the receptacle 10 where the oil is mixed withthe air or gas which is flowing through the body portion 10 and therebyproduces a mixture which will produce an intense heat upon thecombustion of the same. Should it be desired to employ a burner for theburning of gas alone, the valve 26 is closed and the sleeve 12 isrotated, together with the pipe 14, to feed the inlet pipe 1st inwardlytoward the bead 22 whereby the disk 21 will approach the same and reducethe opening into the forward end of the body portion 10 to limit theamount of air or to entirely close the inflow of air into the bodyportion 10. In this arrangement the gas is introduced through the pipe14:, sleeve 16 and nipple 23 into the forward end of the body portion 10where it is discharged and consumed.

It will be noted from Fig. 2 that the sleeve 16 can be regulated toincrease or reduce the distance between the shoulder 18 and the disk 15in order to limit the flow of gas or air into the nipple 23 according tothe requirements and to the conditions under which the burner issubjected. When the disk is seated upon the bead 22 steam may beintroduced into the inlet pipe 1l a-nd led forwardly direct to thenipple 23 'where'it is discharged and is intermingled with a quantity ofhydrocarbon introduced into the body portion 10 through the pipe 25 andcontrolled by the valve 26.

The adjustment of the air inlet through the opening 11 may be easilyobtained by the formation of the sleeve 28 disclosed in Fig. 5 and ofthe provision of the set-screw whereby accurate adjustment may be had.and maintained. This formation is especially applicable where it isnecessary to fre quently change the adjustments of the burner toaccommodate various conditions.
